To all 'whom'fit may concern:

Be it known that I, WILLIAM T1 JONES, Va citizen of the United Statea'residing at Detroit, in the count of Wayne, State of Michigan,have invente' certain new and useful lm4 provements in Lamp-Fount-Attaching 'Devices; and I do declare the following to be a full, clear, and exact description of Ythe inven' tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings ,and tothe figures of reference marked thereon, which form a part of this specificati-on.

'This invention relates .to new and useful improvements inlamps, especially designed for .use in connection with motor vehicles, and Vconsists in the construction and arrangement of parts hereinafter fully set forth and claimed.

vision is made for readily securingL the lamp font to the depending collar of .t e body of the lamp in a manner to prevent accidental release of the looking parts through the jar or.,

vibration incident to the use of the lamp on motor vehicles, the arrangement being such as to hold the lamp font against rotation in the collar and relieve the burner shaft fro'm all lateral strain.

The above object is attained by the structure illustrated in the .accompanying'drawinfie, in whichzigure- 1 is an elevationl of a lamp embodying my invention. Fig. 2 is a horizontal section as on line 2--2 of Fig. 1,. Fig. 3 is a fragmentary view, partl in section, showing the manner of locking t ie font t0 the collar .50 lof the lamp bod Fig. 4 is a similar view 13:7' bolts turned to release showing the loc Ing the font, and said font partially withdrawn. Fi 5 is a perspective view of one of the loc ing bolts within' its embracing` tube. Fig. 6 is a fragmentary view in elevation, showing -a side -view of one of the locking boltsin position as -when securing th`e font to 'the collar of the lamp body.' I

Referring to the characters of reference, 1 desiV nates the body of the lanp which may be of an suitable construction and shape and from w -ch depends a collar 2. The loweil ed -efof the collar is turned inwardly forming a orizontal/ shoulder 3 whose margn is rolled, as shown at 4, and forms the boundary The object of the invention is to produce a;y lamp of the character described, wherein proof a circular opening 5 for the introduction of the up er end of the font. Crossing opposite arcs 0 the circle described by the collar 2 are theV tubes 6 whose ends pass through and are secu-red in the .Wall of said collar, the central ortion of said tubes resting upon and Cross- "Ing thecircular shoulder 3. Passing through the tubes 6 and mounted to turn therein are the locking bolts 7 having 'at one end a right an le arm 8 Lto adord means for turning said 65 bo ts, and at. the other end an elbow 9 to y prevent the withdrawal of said bolts from said tub'es.

' It will be noted that the tubes 6 are s0 positioned. as to cross an arc of the openingy 'zo 5 on opp-lesite? sides thereof, and. thattheinner wa s of said tubes are cut away,fas 'at 10, in a curvilineal lane concentric 'With said circle 5. It will a so be noted that the looking bolts 7. are milled away on one side, 75 as shown at 11, in a manner to register with the openings in theinner walls of said tubes. By this arrangement when the lockingbolts are so turned as to cause their milledportions 11 to register'with'the curved opens0 ings in the inner Walls of the tubes 6, the opening 5 ythrough the collar 2 is unrestricted, permitting the entrance into 'said' collar of an object ofthe full diameter of said open ing. By turning said bolts however, sofas 85- Vpresent their full peripheries inwardly, as siown in Figs. 2 and 3, they will project through the curved openin s in the tubes and willextendas chordal 'nesacross the.- opposite arc'of the opening 5, thereby` re- 9o, strioting the area of said o enin'g.

To utilizeI the rotative ocking bolts for the purpose of securing the lam font 12 A' Within the opening 5 in the colar of theI l i lamp, the wall\of the lamp font near the 'A top thereof is provided with the annular4 semicircular recessfl of a diameter equal to the diameter of said bolts.l The arrangement of the parts is such that when the bolts are turned so as to'4 present their '100- milled faces inwardly to coincide with the curved openings in theA inner Walls .of the tubes,`-as`shown in Fig. 4, the upper end of a lamp font maybe entered in the opening 5 so as to cause vthe circular recess 134 to `105- register with and lie in the plane of said bolts, when by rotating said bolts -the v straight faces thereof opposite the milled portions are caused to turn into said-recess 'on opposite sides, and therebyfii'mly lock. 110` the font within the collai 2 of the lamp, as clearly shown in Fig. 3. l

As the circular recess 13 in which the locking bolts engage is formed in the wall of the lamp font, there is no attached part with which said bolts engage that can possibly become loose and ermit said font to drop out of the collar o the lamp. lt,will also be observed. that by journaling the locking bolts in the wall of said collar and turning the ends thereof in the manner shown, said bolts' cannot work out nor becorne loosened in a manner to impair their operation.

When the bolts are in the position to lock the font 'in the collar of the lamp, the

vright angletarms 8 thereof stand' down wardly, thei'gravity of which assists in retaining said bolts in said locked position and obviates the liability of said bolts becoming accidentally turned so `as to free the font and permit it to 4drop out of the collar.

It will further be noted that the straightl rounded sides of the locking bolts when enterin the recess 13, act as eccentric locks and bear in said recess when in the locked position with sufficient pressure to prevent rattling of the parts. While this manner of securing the font in the collar of the lamp affords a secure and rigid fastenin it is of a character to enable the font to e readily removed when desired, by simply rotating the locking bolts so as to carry the' straight faces thereof from engagement in the recess 13 and present their milled faces inwardly in which position the parts remain until the font is reinserted in the opening in the collar, when by turning the angle arms 8 of the locking bolts downwardly, the font may be again secured in place.

A slot 14 is formed in the collar 2 to ac commodate the wick shaft 15 of the burner.

ST0 relieve the wick shaft from lateral strain by a relative rotary movement between the collar and font, and to maintain the llame of the burner in a proper position with re spect to the glass of the lamp, the vertical lug 16 is mounted in the wall of the lamp font which projects into the slot 14 in thev collar and prevents a possible turning of the font within 'said co collar, the terminals of said bolts exteribr 'to said wall being bent at anangle to the axis h lar, thereby maintaining the parts in their proper relative' and the central portion of said bolts having milled faces concentric with the collar open ing, a lamp font having in the'wall thereof near its upper end a circumferential recess, the upper end of said font entering the opening of the collar and the locking bolts being adapted by a rotation. thereof to engagein said recess in the wall of the font.

2. In a lamp, the combination of a lamp body having a depending annular collar provided at its lower edge with an inwardly projecting horizontal. shoulder, a rotary locking bolt within said collar crossing between opposite portions of the annular wall thereof andjournaled at its ends in said opposite portions of said wall, that portion of the locking bolt intermediate its ends lying upon and supported by said shoulder, and having a mi ed face concentric with the collar opening, a lamp font having a reduced upper portion adapted to enter the o )enin'g of the collar, the wall of said font having a circumferential recess in ,which said locking bolt is adapted to engage, and means for rotating said bolt.

3. In a lamp, the combination of a lam i body having a depending annular collar with a central opening therethrough, a tube within said collar crossing between o posite portions of the annular wall tliercofpand rigidly supported at its ends in said opposite por tions of said wall, said tube having an opening in its inner side concentric with the central opening through the collar, a locking bolt passing through said tube and rotatable therein, that portion of the locking bolt intermediate its ends having a milled face concentric with the collar opening and registering with the opening in said tube, a lamp font having a reduced upper portion adapted to enter the opening of the collar, the wall of said font having a circumferential recess in which 'said locking bolt is adapted to engage when turned to present its straight sido thereto, and means for rotating said bolt.
